"Running with Jon’s Personal Best Training group was a great inspiration and motivation. The training program was very different to what I had been doing the past couple of years and challenged my running abilities as well as mental strength. I entered a new level of athletic competency. Jon’s training helped me with running techniques and racing strategies. What was more important to me was the knowledge that Jon knew what I could potentially do and also having the support from a great training group. Through Jon and PBT, I was able to push physically the hardest I could, keep myself motivated to try the best I had in me, and aim for a goal that felt so far fetched and unbelievable to me."
